Here is a list of purple, as well as lavender, lilac and violet gemstones, arranged from the most expensive to the more affordable.
While most popular for its white variety, diamond also occurs as violet and purple jewels, which are among the rarest of diamonds.

Beside red, taaffeite is the first and only mineral that was discovered after the stone was cut and faceted.

While most popular in red, spinel also occurs as purple stones. Glassy in clarity and luster, this purple semi-precious stone is pale in intensity, and therefore appears lavender or lilac rather than actually purple. Pegged at 7.5 to 8 in the Mohs scale, the purple crystal is quite hard and durable, making the purple gem very suitable for jewelry.
While also found in blue, tanzanite is most popularly known to occur as purple stones, and is the modern exemplification of purple gemstones. Discovered only in 1967 in Tanzania (hence the name tanzanite), this purple crystal is a variety of zoisite, which is a glassy mineral also found in green and yellow. Tanzanite has become quite a popular purple gem that the relatively new gemstone was designated as modern birthstone for December.
Often made a substitute to diamond, zircon is an excellent gemstone, be it in terms of clarity, luster or hardness. While most popular in blue, zircon also occurs as purple stones. Zircon is a traditional birthstone for December. In astrology, the gemstone is associated with the zodiac sign Virgo.
Idocrase is an alternate name for the mineral vesuvianite. Beside yellow and green, idocrase also occurs as purple stones. This purple crystal gets its color from manganese inclusion. For that reason, the purple stone is separately identified in mineralogy as mangan-vesuvianite.
Beside blue, iolite also occurs as violet stones. In fact, the name iolite comes from the Greek for “violet.” Known in mineralogy as cordierite, this violet gem may be bluish in shade. The violet stone can be glassy in clarity and luster, with a hardness of 7 to 7.5 in the Mohs scale.

Kunzite is the violet variety of spodumene, as hiddenite is the green.
